Efficacy, safety and immunogenicity of a recombinant human papillomavirus bivalent (types 16, 18) vaccine in healthy 18-30-year-old Chinese women: a phase III, double-blind, randomized, controlled trial.

ABSTRACT:

Background

Affordable HPV vaccines are needed to accelerate elimination of cervical cancer. We evaluated the efficacy, safety, and immunogenicity of a recombinant bivalent human papillomavirus (HPV) vaccine composed of L1 virus-like particles (VLPs) for HPV 16 and HPV18 (HPV-2), produced in Pichia pastoris, in healthy Chinese women aged 18-30 years.

Methods

In this phase 3, double-blind, randomised, placebo-controlled trial conducted at 10 centres in China (Nov 2014-Jan 2020), participants were assigned 1:1 to receive three doses of HPV-2 or placebo at months 0, 2, and 6. The primary endpoint was efficacy against histopathology-confirmed cervical intraepithelial neoplasia grade 2 or higher (CIN2+) associated with HPV16/18 through 48 months. Secondary endpoints were safety (a
